I mentioned previously how useful Launchbar is for keyboard junkies. Another neat feature is the way it can jump to a particular pane of the System Preferences.
For example, to get to the Network Pane from whatever application I am working in, I key the following
alt-spacebar
network<enter>
and the System Preferences Application is displayed (or started if it is not currently running) with focus on the Network Preference Pane.
